Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

FIG. 1 is a schematic diagram illustrating a camera assembly, as shown in FIG. 1, for externally connecting to a mobile phone and providing a camera function for the mobile phone, according to an exemplary embodiment; the camera assembly includes: an interface circuit 110, a camera 120 connected to the interface circuit 110;

and a camera 120 for photographing under the control of the control signal transmitted from the interface circuit 110.

The number of the interface circuits 110 in the camera assembly is at least one, and fig. 1 illustrates an example in which the camera assembly includes two interface circuits 110.

It should be noted that the camera 120 in this embodiment may be an analog camera, pixels of the analog camera are higher than pixels of the digital camera, and the analog camera includes an analog circuit and a digital circuit.

In summary, according to the camera assembly provided by the present disclosure, the camera can be connected to the mobile phone through the interface circuit instead of being fixed on the front panel of the mobile phone, so that the problem that the screen occupation ratio of the full-screen is affected by installing the camera on the front panel is solved, and the effect of improving the screen occupation ratio of the full-screen is achieved.

Fig. 2 is a schematic diagram illustrating a camera control system according to an exemplary embodiment, which includes a camera assembly 210 and a cell phone 220, as shown in fig. 2. Wherein, this camera subassembly 210 includes: an interface circuit 211, a camera 212 connected to the interface circuit 211; the mobile phone 220 includes: an image pickup interface circuit 221. At this time, the camera assembly 210 is externally connected to the mobile phone 220 and provides a shooting function for the mobile phone 220.

The interface circuit 211 is matched with the camera interface circuit 221, that is, the interface circuit 211 can be inserted into the camera interface circuit 221, and at this time, each transmission line in the interface circuit 211 is connected with a corresponding transmission line in the camera interface circuit 221, so as to realize communication between the camera module 210 and the mobile phone 220. In this embodiment, the connection means electrical connection, and will not be described in detail below.

The number of the interface circuits 211 is equal to the number of the image pickup interface circuits 221, and the number of the interface circuits 211 and the image pickup interface circuits 221 is not limited in this embodiment. If the number of the interface circuits 211 and the camera interface circuits 221 is 1, when the camera assembly 210 is used, only one interface circuit 211 needs to be inserted into one camera interface circuit 221, so that the connection operation between the camera assembly 210 and the mobile phone 220 can be simplified. If the number of the interface circuits 211 and the camera interface circuits 221 is greater than 1, all the interface circuits 211 need to be inserted into the corresponding camera interface circuits 221 when the camera assembly 210 is used, and since each set of the interface circuits 211 and the camera interface circuits 221 can be used as a supporting point for the camera 212, the connection stability between the camera 212 and the mobile phone 220 can be improved. Further, since signals can be branched by at least two sets of the interface circuit 211 and the image pickup interface circuit 221, communication pressure of the interface circuit 211 and the image pickup interface circuit 221 is reduced.

The number of the transmission lines in the interface circuit 211 is equal to the number of the transmission lines in the image pickup interface circuit 221, but the number of the transmission lines in the interface circuit 211 and the image pickup interface circuit 221 is not limited in this embodiment. The transmission line may be implemented by a wire having a relatively high rigidity, and the camera 212 may be supported by the transmission line, thereby implementing a function of a cradle by the transmission line. Alternatively, a stand may be provided to support the camera 212 via the stand, which is not limited in this embodiment.

In this embodiment, the camera assembly 210 and the mobile phone 220 can perform two-way communication, and the following describes the two-way communication process.

In a first communication mode, when the mobile phone 220 sends data to the camera assembly 210, the camera interface circuit 221 is configured to be connected to the camera assembly 210 to implement an interface function, read and transmit a control signal generated by the mobile phone 220 to the camera assembly 210, and implement camera control on the camera assembly 210; an interface circuit 211, which is used for connecting with the mobile phone 210 to realize an interface function, and outputting a control signal obtained from the mobile phone 220 to the camera 212; and a camera 212 for photographing under the control of the control signal transmitted from the interface circuit 211.

Referring to fig. 3, the interface circuit 211 includes a communication transmission line 2111, and the communication transmission line 2111 is a bidirectional transmission line, that is, the communication transmission line 2111 can both transmit signals to the mobile phone 220 and receive signals from the mobile phone 220; the camera interface circuit 221 includes a communication transmission line 2211, and the communication transmission line 2211 is a bidirectional transmission line, i.e., the communication transmission line 2211 can both transmit signals to the camera assembly 210 and receive signals from the camera assembly 210. Communication transmission line 2111 is connected to communication transmission line 2211. At this time, the control signal generated by the mobile phone 220 sequentially passes through the communication transmission line 2211 and the communication transmission line 2111 to the camera 212. The communication transmission line 2111 and the communication transmission line 2211 may be copper wires or other lines, and this embodiment is not limited thereto.

The upper half of fig. 3 is a schematic configuration diagram of the interface circuit 211, and the lower half is a schematic configuration diagram of the image pickup interface circuit 221.

The control signal may be obtained by the user operating the mobile phone 220, for example, the control signal may be obtained by the user clicking a camera icon in the mobile phone 220, and the operation performed by the camera 212 is to open the camera 212 at this time; the control signal may be obtained by the user adjusting the zoom ratio of the preview image in the mobile phone 220, and the operation performed by the camera 212 at this time is to adjust the focal length; the control signal may be obtained by the user clicking a video recording control in the mobile phone 220, and the operation performed by the camera 212 is to switch from the photographing mode to the video recording mode. Of course, the user may also control the camera 212 to perform other operations, and the embodiment is not limited.

In a second communication mode, when the camera module 210 sends data to the mobile phone 220, the interface circuit 211 is used for connecting with the mobile phone 220 to implement an interface function, and reading and transmitting image data shot by the camera 212 to the mobile phone 220; the camera interface circuit 221 is configured to be connected to the camera assembly 210 to implement an interface function, and output image data acquired from the camera assembly 210 to the mobile phone 220 to implement image reading control on the camera assembly 210.

The interface circuit 211 includes a data transmission line 2112, the image pickup interface circuit 221 includes a data read line 2212, and the data transmission line 2112 is connected to the data read line 2212. At this time, the image data captured by the camera 212 sequentially passes through the data transmission line 2112 and the data reading line 2212 to the mobile phone 220.

Since the pixels of the camera 212 are high, the data amount of the photographed image data is large, and a plurality of data transfer lines and a plurality of data reading lines may be provided at this time, so that the image data is transferred in parallel through the plurality of data transfer lines and the data reading lines to improve the transfer efficiency. In a possible implementation manner, the number of the data transmission lines and the number of the data reading lines may be 10, and the embodiment is not limited.

The configurations of the interface circuit 211 and the image pickup interface circuit 221 will be described below.

1) The interface circuit 211 includes a power line 2113 for receiving power from the mobile phone 220 after being connected to the mobile phone 220 to provide power to the camera module 210; the image pickup interface circuit 221 includes a power supply unit 2213 for outputting power to the externally connected camera module 210.

In this embodiment, the camera assembly 210 may have its own power supply, and since aging of the power supply may affect the service life of the camera assembly 210, optionally, the camera assembly 210 may also be powered by the mobile phone 220. At this time, the interface circuit 211 further includes a power supply line 2113, the image pickup interface circuit 221 further includes a power supply unit 2213, and the power supply line 2113 is connected to the power supply unit 2213. At this time, the power supply in the mobile phone 220 sequentially passes through the power supply unit 2213 and the power line 2113 to the camera assembly 210 to supply power to the camera assembly 210.

In this embodiment, when the power supply is unstable, the conductivity of the semiconductor device in the camera 212 is affected, and thus the imaging effect of the camera 212 is affected, so the power supply unit 2213 may include a voltage-stabilizing sub-unit for stabilizing the voltage via the BUCK conversion BUCK circuit and an output sub-unit; and the output subunit is used for outputting the voltage subjected to voltage stabilization processing to the external camera assembly 210, so that the imaging effect of the camera 212 is improved through the BUCK circuit. The BUCK circuit is used for adjusting the output energy according to the load size, so that the energy in the load is ensured to be constant. The Semiconductor device may be a diode, a triode, a MOS (Metal-Oxide-Semiconductor) transistor, and the like, and the embodiment is not limited thereto.

Referring to fig. 3, the interface circuit 211 further includes three power lines 2113, the image pickup interface circuit 221 further includes three power supply units 2213, and each power line 2113 is connected to one power supply unit 2213. At this time, one path of power supply respectively passes through one power supply unit 2213 and the power line 2113 to the camera 212; one path of power supply respectively passes through a power supply unit 2213 and a power line 2113 to the analog circuit in the camera assembly 210; one path of power is supplied to the motor circuit 213 through a power supply unit 2213 and a power line 2113, respectively. The analog circuit is configured to collect an analog signal of image data captured by the camera 212, output the analog signal to the interface circuit 211, and process the analog signal into image data by the interface circuit 211 for output.

The first point to be noted is that a capacitor may be further provided at the power line 2113 to avoid the influence of the ripple on the circuit. Optionally, capacitance locations may also be reserved at the power supply line 2113, so that when the ripple is large, capacitances may be provided at these capacitance locations.

The second point to be noted is that when the power supply in the mobile phone 220 supplies power to the camera 212, the power line from the power supply to the camera 212 is long and has a certain impedance, so that the voltage drop of the power supply is affected, and therefore, the ripple applied to the power supply of the camera 212 may be large. At this time, in addition to ensuring that the energy in the load is constant by the BUCK circuit, the impedance of the power supply line can be limited. For example, the impedance of the power line may be limited to be greater than a predetermined impedance threshold, or the thickness of the power line may be limited to reach a predetermined thickness threshold, and the like, which is not limited in this embodiment.

2) The interface circuit 211 includes an ID signal transmission line 2114 for supplying an ID signal recognizable by the cellular phone 220; the image pickup interface circuit 221 includes an ID signal read line 2214 for acquiring an ID signal of the camera head assembly 210.

Since the imaging effect of the camera 212 is related to the pixels, in order to ensure that the image data captured by the camera 212 can be clearly displayed in the mobile phone 220, the pixels of the camera 212 need to be limited. In one possible implementation, the pixels of camera 212 may be restricted by an ID (Identity) signal of camera 212.

In a possible implementation manner, if an ID signal of the camera 212 whose pixel reaches a preset value can be preset, the mobile phone 220 may verify the ID signal of the camera 212 in the accessed camera assembly 210, and when the ID signal is the preset ID signal, the mobile phone 220 may identify the ID signal, determine that the pixel of the camera 212 reaches the preset value, and identify the camera 212; when the ID signal is not the preset ID signal, the mobile phone 220 cannot recognize the ID signal, and determines that the pixel of the camera 212 does not reach the preset value, i.e., does not recognize the camera 212.

In transmitting the ID signal, the interface circuit 211 includes an ID signal transmission line 2114, the image pickup interface circuit 221 includes an ID signal read line 2214, and the ID signal transmission line 2114 is connected to the ID signal read line 2214. At this time, the ID signal of the camera 212 sequentially passes through the ID signal transmission line 2114 and the ID signal reading line 2214 to the mobile phone 220.

3) The interface circuit 211 includes a clock signal read line 2115 for acquiring a clock signal from the cellular phone 220 to provide a clock for the camera assembly 210; the camera interface circuit 221 includes a clock signal transmission line 2215 for outputting a clock signal to the camera assembly 210.

Since the configuration parameters of the camera assembly 210 are different for different pixels, the cell phone 220 can also configure the clock of the camera assembly 210 according to the ID signal. At this time, the interface circuit 211 includes a clock signal read line 2115, the image pickup interface circuit 221 includes a clock signal transmission line 2215, and the clock signal read line 2115 is connected to the clock signal transmission line 2215. At this time, the mobile phone 220 sequentially transmits the clock signal determined according to the ID signal to the camera module 210 through the clock signal transmission line 2225 and the clock signal reading line 2215 to provide a clock for the camera module 210.

Optionally, the mobile phone 220 may further determine a driving signal of the camera assembly 210 according to the ID signal, and the driving signal sequentially passes through the communication transmission line 2211 and the communication transmission line 2111 to the camera assembly 210 to provide driving parameters for the camera assembly 210.

The mobile phone 220 may be pre-stored with the mapping relationship between the ID signal, the clock signal, and the driving signal, and the mobile phone 220 may determine the corresponding clock signal and the driving signal according to the ID signal. Where the clock signal is associated with the pixels of camera 212, i.e., the higher the pixel the faster the clock, the lower the pixel the lower the clock. The driving signal is used to configure driving parameters, such as the transmission rate of the data transmission line 2112 and the data read line 2212, and the like, and the embodiment is not limited.

The interface circuit 211, after determining the processing speed of the image data according to the clock signal and configuring the driving parameters according to the driving signal, is equivalent to activating the camera 212, at which time the user can use the camera 212.

It should be noted that, because the data transmission/reading line and the clock signal transmission/reading line between the camera 212 and the mobile phone 220 are longer in routing, and a high-speed signal is transmitted in the data transmission/reading line and the clock signal transmission/reading line, which is easy to cause reflection and attenuation of the high-speed signal, an amplifier circuit and an EMI (electromagnetic Interference) circuit may be further added to the mobile phone 220 to compensate for the reflection and attenuation of the high-speed signal.

4) The interface circuit 211 includes an abnormal flag signal transmission line 2116 for providing an abnormal flag signal recognizable by the mobile phone 220; the image pickup interface circuit 221 includes an abnormal flag signal read line 2216 for acquiring an abnormal flag signal of the camera head assembly 210.

When an exception occurs, the exception also needs to be handled. The abnormality may be caused by an abnormality of the camera head assembly 210 itself, such as an increase in temperature due to excessive power consumption of the camera head 212, damage due to ESD (Electro-Static discharge), and the like. The abnormality may also be generated because the camera assembly 210 cannot receive the signal sent by the mobile phone 220, for example, the interface circuit 211 may determine that the camera assembly 210 is abnormal when image data is continuously sent to the mobile phone 220 and no response signal returned by the mobile phone 220 is received for more than a predetermined time; alternatively, the interface circuit 211 may determine that the mobile phone 220 is abnormal when the image data is not transmitted to the mobile phone 220 and the control signal transmitted by the mobile phone 220 is not received for more than a predetermined time. The occurrence of an abnormality in the camera assembly 210 will be described as an example.

In one possible implementation, the interface circuit 211 includes an abnormal flag signal transmission line 2116, the image pickup interface circuit 221 includes an abnormal flag signal read line 2216, and the abnormal flag signal transmission line 2116 is connected to the abnormal flag signal read line 2216. At this time, the abnormal flag signal generated by the interface circuit 211 sequentially passes through the abnormal flag signal transmission line 2116 and the abnormal flag signal reading line 2216 to the mobile phone 220.

After receiving the abnormal flag bit signal, the mobile phone 220 may generate a processing signal, and the processing signal sequentially passes through the communication transmission line 2211 and the communication transmission line 2111 to the camera assembly 210 to indicate a processing manner of the camera assembly 210 for the abnormality.

When there is only one processing signal, the processing signal typically instructs the camera 212 to restart to avoid creating more serious problems, thereby increasing the success rate of exception handling. Since the user experience is influenced by restarting, various abnormal grades can be set according to the severity of the abnormality, different abnormal signals are set according to different abnormal grades, and therefore abnormal processing modes which do not disturb the user, such as resetting and the like, are carried out when the abnormality is not serious, so that the user is prevented from being disturbed; and when the abnormity is serious, an abnormity processing mode of restarting the camera 212 is carried out so as to improve the success rate of processing the abnormity.

In this case, the interface circuit 211 is further configured to determine an abnormality level of the abnormality, and generate an abnormality flag signal corresponding to the abnormality level, where the voltage values of the abnormality flag signals corresponding to different abnormality levels are different. The image pickup interface circuit 221 further includes a sampling circuit 2217, and the sampling circuit 2217 is connected to the abnormal flag signal reading line 2216, and samples the voltage value of the abnormal flag signal read in the abnormal flag signal reading line 2216, so that the mobile phone 220 can determine the abnormal processing mode for the camera assembly 210 according to the sampled voltage value. The sampling circuit 2217 may be an ADC (Analog-to-Digital Converter) sampling circuit, or may be another sampling circuit, and the embodiment is not limited thereto.

Different voltage values can be set for different abnormal levels in advance, for example, the voltage value of the abnormal level at the time of restarting is 1.8V, the voltage value of the abnormal level at the time of power-off reset is 1.5V, and the like.

If the mobile phone 220 is abnormal, the mobile phone 220 may process the abnormality according to the abnormal flag bit signal after receiving the abnormal flag bit signal, without generating a processing signal to send to the camera assembly 210.

5) The interface circuit 211 comprises a first protection circuit 2117, which is used for controlling the camera assembly 210 to be in a power-off state when the interface circuit 211 is wet and controlling the camera assembly 210 to be in a power-on state when the interface circuit 211 is dry after being connected with the mobile phone 220; the camera interface circuit 221 includes a bias circuit 2218 for controlling the camera assembly 210 to be in a power-off state when the interface circuit 211 in the camera assembly 210 is wet and controlling the camera assembly 210 to be in a power-on state when the interface circuit 211 in the camera assembly 210 is dry after being connected to the camera assembly 210. That is, the combination of the first protection circuit 2117 and the bias circuit 2218 has a waterproof function to ensure that the interface circuit 211 and the image pickup interface circuit 221 can be normally used.

With respect to the combination of the first protection circuit 2117 and the bias circuit 2218, referring to fig. 4, in one implementation, the first protection circuit 2117 may include foam, and the mobile phone 220 is configured to generate a short-circuit signal when the bias circuit 2218 is short-circuited under the control of the foam in a wet state; the camera assembly 210 is in a powered down state under the control of a short circuit signal generated by the cell phone 220. Or, the mobile phone 220 is configured to generate a disconnection signal when the bias circuit 2218 is disconnected under the control of the foam in the dry state; the camera assembly 210 is in a powered-on state under control of a power-off signal generated by the cell phone 220.

The bias circuit 2218 includes a bias voltage and a bias resistor, and a voltage signal is always present on the bias voltage. When the foam is in a dry state, the volume of the foam is small, and the bias resistor in the bias circuit 2218 cannot be grounded, so that the bias circuit 2218 is disconnected, and no power is consumed, and at this time, the mobile phone 220 generates a disconnection signal and controls a power supply and the like to supply power to the camera assembly 210. When the foam is in a wet state, the foam has a large volume, and the bias resistor in the bias circuit 2218 can be grounded, so that the bias circuit 2218 is short-circuited, and at this time, the mobile phone 220 generates a short-circuit signal and controls a power supply and the like to not supply power to the camera assembly 210. The foam expands in volume after being wetted, namely the area of the foam in a wet state is larger than that of the foam in a dry state.

Optionally, when the foam is in a wet state, the moisture in the foam may be squeezed or dried, so that when the foam is in a dry state, the interface circuit 211 is inserted into the camera interface circuit 221 for use.

6) The interface circuit 211 includes a second protection circuit 2118 for filtering an instantaneous ac voltage signal input from the cellular phone 220.

In this embodiment, the second protection circuit 2118 has an antistatic function to ensure that the interface circuit 211 and the image pickup interface circuit 221 can be used normally.

Since there is a risk of entering dust, heat generation, ESD, or the like at the interface circuit 211, the second protection circuit 2118 needs to be provided in the interface circuit 211. Since the camera assembly 210 is supplied with the dc voltage signal and the static electricity is the instantaneous ac voltage signal, the second protection circuit 2118 filters the instantaneous ac voltage signal without affecting the dc voltage signal, thereby ensuring the normal use of the camera assembly 210.

Fig. 5 is a flowchart illustrating a camera assembly control method applied to a camera control system according to an exemplary embodiment, and the camera assembly control method includes the following steps, as shown in fig. 5.

In step 501, the mobile phone generates a control signal and transmits the control signal to the camera assembly, where the control signal is used to control the camera assembly to shoot.

In step 502, the camera assembly outputs a control signal acquired from the mobile phone to the camera, and performs shooting under the control of the control signal.

In step 503, the camera assembly reads and transmits image data captured by the camera to the mobile phone.

In step 504, the handset acquires image data from the camera assembly.

Wherein, steps 501 and 504 can be implemented separately as the method embodiment of the mobile phone side, and step 502 and 503 can be implemented separately as the method embodiment of the camera assembly side.

In summary, according to the camera module control method provided by the disclosure, the camera can be connected to the mobile phone through the connecting line and the interface circuit instead of being fixed on the front panel of the mobile phone, so that the problem that the screen occupation ratio of the full screen is affected by mounting the camera on the front panel is solved, and the effect of improving the screen occupation ratio of the full screen is achieved.

Fig. 6 is a flowchart illustrating a camera assembly control method applied to a camera control system according to another exemplary embodiment, and the camera assembly control method includes the following steps, as shown in fig. 6.

In step 601, the mobile phone outputs power to an externally connected camera module.

In step 602, the camera assembly obtains power from the handset to provide power to the camera assembly.

In this embodiment, the camera component can be provided with a power supply, and the aging of the power supply can affect the service life of the camera component, so that the camera component can be optionally powered by a mobile phone. Since the power line from the power supply to the camera is long and has a certain impedance, the voltage drop of the power supply is affected, and therefore, the ripple of the power supply applied to the camera may be large. At this time, in addition to ensuring that the energy in the load is constant by the BUCK circuit, the impedance of the power supply line can be limited. For example, the impedance of the power line may be limited to be greater than a predetermined impedance threshold, or the thickness of the power line may be limited to reach a predetermined thickness threshold, and the like, which is not limited in this embodiment.

At the moment, the voltage of the mobile phone is subjected to voltage stabilization treatment through a BUCK circuit; outputting the power supply subjected to voltage stabilization treatment to an externally connected camera assembly; the camera component obtains the power supply after voltage stabilization from the mobile phone.

In step 603, the camera assembly outputs an ID signal that can be recognized by the handset to the handset.

Because the imaging effect of the camera is related to the pixels, in order to ensure that the image data obtained by shooting by the camera can be clearly displayed in the mobile phone, the pixels of the camera need to be limited. In one possible implementation, the pixels of the camera may be limited by the ID signal of the camera.

Because the configuration parameters of the cameras of different pixels are different, the mobile phone can also configure the cameras according to the ID signals.

Whether the ID signal is used to identify the camera or the configuration parameters, the camera assembly needs to output the ID signal to the handset, which output flow is detailed in the embodiment shown in fig. 2.

In step 604, the mobile phone obtains an ID signal of the camera assembly; and determining a clock signal and a driving signal according to the ID signal, and outputting the clock signal and the driving signal to the camera assembly.

When the ID signal is used for identifying the camera, the ID signal of the camera with the pixel reaching the preset value can be preset in the mobile phone, the mobile phone can verify the ID signal of the camera in the accessed camera assembly, and when the ID signal is the preset ID signal, the mobile phone can identify the ID signal and determine that the pixel of the camera reaches the preset value, namely the camera is identified; when the ID signal is not the preset ID signal, the mobile phone cannot identify the ID signal, and the pixel of the camera is determined not to reach the preset numerical value, namely the camera is not identified.

When the ID signal is used to identify the configuration parameter, the mobile phone may pre-store the mapping relationship between the ID signal, the clock signal, and the driving signal, and then the mobile phone may determine the corresponding clock signal and driving signal according to the ID signal. Wherein the clock signal is related to the pixels of the camera, i.e. the higher the pixel the faster the clock, the lower the pixel the lower the clock. The driving signal is used to configure driving parameters, such as the transmission rate of the data transmission line, and the like, and the embodiment is not limited.

In step 605, the camera assembly acquires a clock signal and a driving signal from the mobile phone; determining the processing speed of the image data according to the clock signal; drive parameters in the camera assembly are configured according to the drive signals.

After the interface circuit in the camera assembly determines the processing speed according to the clock signal and configures the driving parameters according to the driving signal, the camera is activated, and the user can use the camera at the moment.

In this embodiment, the camera assembly and the mobile phone can implement two-way communication, wherein the step 606-.

In step 606, the mobile phone generates a control signal and transmits the control signal to the camera assembly, where the control signal is used to control the camera assembly to shoot.

The control signal may be obtained by a user operating the mobile phone, for example, the control signal may be obtained by the user clicking a camera icon in the mobile phone, and the operation executed by the camera is to open the camera at this time; the control signal can be obtained by adjusting the scaling of a preview picture in the mobile phone by a user, and the operation executed by the camera at the moment is to adjust the focal length; the control signal may be obtained by a user clicking a video recording control in the mobile phone, and at this time, the operation executed by the camera is switched from the photographing mode to the video recording mode. Of course, the user may also control the camera to perform other operations, and this embodiment is not limited.

In step 607, the camera module outputs a control signal acquired from the cellular phone to the camera, and performs shooting under the control of the control signal.

In step 608, the camera assembly reads and transmits image data captured by the camera to the mobile phone.

Because the pixels of the camera are higher, the data volume of the image data obtained by shooting is larger, and a plurality of data transmission lines can be arranged at the moment, so that the transmission efficiency is improved by transmitting the image data in parallel through the plurality of data transmission lines.

In step 609, the handset acquires image data from the camera assembly.

When an exception occurs, the exception also needs to be handled. The abnormality may be caused by an abnormality of the camera assembly itself, such as an excessive power consumption of the camera head resulting in a temperature rise, a damage due to ESD, or the like. The abnormality may also be generated because the camera assembly cannot receive a signal sent by the mobile phone, for example, the interface circuit may determine that the camera assembly is abnormal when image data is continuously sent to the mobile phone and a response signal returned by the mobile phone is not received for more than a predetermined time; or, the interface circuit may determine that the mobile phone is abnormal when the image data is not sent to the mobile phone and the control signal sent by the mobile phone is not received after a predetermined time period. The steps 610 and 612 are described by taking the camera assembly as an example.

In step 610, the camera assembly transmits an abnormal flag signal that can be recognized by the handset to the handset.

The flow of the camera assembly outputting the abnormal flag bit signal to the mobile phone is described in the embodiment shown in fig. 2.

When only one processing signal exists, the mobile phone usually indicates to restart the camera to avoid generating more serious problems, thereby improving the success rate of exception handling. Since the user experience is influenced by restarting, various abnormal grades can be set according to the severity of the abnormality, different abnormal signals are set according to different abnormal grades, and therefore abnormal processing modes which do not disturb the user, such as resetting and the like, are carried out when the abnormality is not serious, so that the user is prevented from being disturbed; and when the abnormity is serious, an abnormity processing mode of restarting the camera is carried out so as to improve the success rate of processing the abnormity.

In this case, generating an abnormal flag signal when the camera is abnormal includes: determining an anomaly level of the anomaly; and generating an abnormal zone bit signal according to the abnormal grade, wherein the voltage values of the abnormal zone bit signals corresponding to different abnormal grades are different.

In step 611, the mobile phone obtains an abnormal zone bit signal of the camera assembly; generating a processing signal according to the abnormal zone bit signal; and outputting the processing signal to the camera assembly.

Wherein, according to unusual flag bit signal generation processing signal, include: sampling the voltage value of the abnormal zone bit signal; and determining the abnormal grade of the abnormal zone bit signal according to the voltage value obtained by sampling, and generating a processing signal corresponding to the abnormal grade, wherein the voltage values of the abnormal zone bit signals corresponding to different abnormal grades are different. The sampling circuit here may be an ADC sampling circuit, or may be another sampling circuit, and this embodiment is not limited thereto.

If the mobile phone is abnormal, the mobile phone can process the self-existing abnormality according to the abnormal zone bit signal after receiving the abnormal zone bit signal, and does not need to generate a processing signal to send to the camera assembly.

In step 612, the camera assembly obtains a processed signal from the handset; the exception is handled according to the processed signal.

In this embodiment, the shooting angle of the camera may also be adjusted, and the shooting angle may be a horizontal shooting angle or a vertical shooting angle. When the horizontal shooting angle of the camera is rotated by 180 degrees, the camera can be converted from a front camera to a rear camera for use, or the camera can be converted from the rear camera to the front camera for use, so that only one camera can be configured in the mobile phone, and the manufacturing cost of the mobile phone is reduced. The adjustment of the photographing angle will be described in steps 613-614.

In step 613, the mobile phone generates an angle adjustment signal; the angular adjustment signal is transmitted to the camera assembly.

The angle adjustment signal can be generated by displaying a preset icon on the mobile phone and clicking the preset icon by the user, wherein the preset icon can be a remote sensing icon. Optionally, the mobile phone may be provided with remote sensing icons in different directions, for example, a remote sensing icon turned to the left and a remote sensing icon turned to the right, a remote sensing icon turned upwards or a remote sensing icon turned downwards.

In step 614, the camera assembly obtains an angle adjustment signal from the mobile phone; and adjusting the shooting angle of the camera according to the angle adjusting signal.

In addition to the above design, in this embodiment, a first protection circuit may be disposed in the camera module, and a bias circuit may be disposed in the mobile phone, and the combination of the first protection circuit and the bias circuit has a waterproof function. At this time, the camera assembly is controlled to be in a power-off state when the interface circuit in the camera assembly is wet, and the camera assembly is controlled to be in a power-on state when the interface circuit in the camera assembly is dry.

In one possible implementation, when the bias circuit is short-circuited under the control of the foam in a wet state, the mobile phone generates a short-circuit signal, and the short-circuit signal is used for controlling the camera assembly to be in a power-off state; when the bias circuit is in open circuit under the control of the foam in the dry state, the mobile phone generates an open circuit signal, and the open circuit signal is used for controlling the camera assembly to be in the power-on state. Wherein the area of the foam in a wet state is larger than the area of the foam in a dry state.

The bias circuit comprises a bias voltage and a bias resistor, and a voltage signal is always on the bias voltage. When the foam is in a dry state, the volume of the foam is small, and the bias resistor in the bias circuit cannot be grounded, so that the bias circuit is disconnected and does not consume power, and at the moment, the mobile phone generates a disconnection signal and controls a power supply and the like to supply power to the camera assembly. When the foam is in a wet state, the foam is large in size and can ground a bias resistor in the bias circuit, so that the bias circuit is short-circuited, and at the moment, the mobile phone generates a short-circuit signal and controls a power supply and the like to supply power to the camera assembly. The foam expands in volume after being wetted, namely the area of the foam in a wet state is larger than that of the foam in a dry state.

Optionally, when the foam is in a wet state, the moisture in the foam can be squeezed or dried, so that when the foam is in a dry state, the interface circuit in the camera assembly is inserted into the interface circuit in the mobile phone for use.

Steps 601, 604, 606, 609, 611, 613 can be implemented separately as method embodiments on the mobile phone side, and steps 602, 603, 605, 607, 608, 610, 612, 614 can be implemented separately as method embodiments on the camera assembly side.

The clock signal and the driving signal are determined through the ID signal, different configuration parameters can be set for different cameras, and therefore normal operation of the cameras is guaranteed.

Different exception grades can be set aiming at exceptions with different severity degrees by setting a plurality of exception grades, so that different processing modes are set for the exceptions with different exception grades, the disturbance to a user can be avoided, and the success rate of exception handling can be improved.
